Yakabvaruka nguva bhandi: zvirango uye chii kuita inotevera?

20 apfuura anenge ose michina iiswe riini cheni tikachirega. Kushandiswa toothed mabhandi panguva akaita vatyairi vazhinji zvakandivhiringidza. Uye hakuna munhu haana kumbofungidzira kuti mashoma apfuura kuri ichi zvakagadzirwa ichashandiswa dzose ano mota. Manufacturers kutsanangura chokwadi chokuti bhandi, mukusiyana kuti cheni kushoma ruzha, ane mano marongerwo uye diki uremu. Zvisinei, hapana huchavapo nokusingaperi. Zvakadini kana chakabvamburanyiwa yokunyatsochengeta nguva bhandi? On ichi uye kwete chete - gare gare munyaya ino.

Akasiyana kubva cheni ngarurege

Panguva nokushanda cheni nemotokari iri kushanda hapana kusakara. Iye sezvo zvikuru uye injini pacharo. Hongu, zviri zvikuru ruzha, dzimwe nguva, zvisinei akatambanudza, mukusiyana kuti bhandi haazombokanganisi vapedzisire uye restarts ake. hazvifaniri kuita Stretch redunhu. Kana bhandi anofanira nguva akasungirirwa. Uye isina kukodzera ruoko anogona kukonzera kukanganisa pamusoro mazino. Nokuda kwaizvozvi, injini hakushandi, uye upfumi chinhu zviri kuderedzwa.

Ita mavharuvhu nokudzvinyirirwa?

Pakati vatyairi pane maonero kuti kana nguva "Reno" bhandi vakaputsa, pakarepo kumanikidza mavharuvhu. Izvi pamwe wechokwadi. Asi kwete nguva dzose. Zvose zvinoenderana kunzwisisa injini kugadzirwa. Kana ichi "shesnar" Zvechokwadi achandipfugamira vharafu. Cars idzo 2 mavharuvhu por humburumbira (Inlet uye nzira yokubudisa ukuwo), vanoonekwa zvikuru yakavimbika panyaya iyi. Asi zvino zvakare, pane kunze (tora Somuenzaniso, Soviet "masere", 1,3-fő carburetor). Kana nengetani zvinhu nyore zvikuru. Anotanga mhete. Uye ruzha ichi irambe kwenguva refu - mumwe, vaviri, makiromita zviuru zvitatu. Up kusvikira zvino, kusvikira muridzi motokari haasi kuneta inzwi, uye haangakuregei vakasvika pakugumisa kuti chinhu chakaipa pano. Chain, kusiyana bhandi, zviri chaizvo "akaoma musoro" panyaya iyi.

Chii chinombodiwa kutungamirira?

Kana iwe akaputsa yokunyatsochengeta nguva bhanhire, zvinokonzerwa zvinogona zvakasiyana. Sezvatakamboreva kare, izvozvo zvose kunobva simba chikwata kugadzirwa. Pano unogona kutungamirirwa nheyo "ari nyore injini, zvikuru murichengete riri." Kana injini riri TDC vharafu pisitoni kunosvika pasi, hapana chichaitika. Panyaya iyi, kana nguva bhanhire akamedura, chete kutenga idzva chigadzirwa inogona nezvaro zvekushandisa. mavharuvhu All ikaramba yakasimba, pasina kukuvadza tsvimbo geometry. Asi kwete nguva dzose kuputswa bhandi kunoitika pamwe zvishomanana kuungana. Kana motokari yako rinoshandiswa zviviri yaunodya uye pedza mavharuvhu por humburumbira (ndiro akawanda motokari pasi 2000s), iri kumusoro mukana kuti richakuteverera. Kushandiswa nguva zvakagadzirwa zvakadai inoendeswa kuwedzera simba. Zvisinei, kana nguva bhandi vakaputsa, zvichaitika zvakasuwa. Panyaya iyi, iyo camshafts (izvo zviviri) kumbomira nzvimbo uko breakage zvakaitika. Flywheel, anosimudzirwa inertia, ari crankshaft rotates, nokuda iyo pane kudhumhana pamusoro pisitoni netsvimbo. Kana kukundikana ndepana usimbe uye kwazvakarerekera, achaita kukanganisa 2-3 zvinhu. Kana nguva bhandi (16 mavharuvhu) akaputsa mudambudziko (uye panguva kumhanya, kunoitika muna 90 muzana nyaya), zvose pezvokuvamba joko pasina anosara. Kudzitsiva, zvinoda dismantling humburumbira musoro. Asi kunyange kana paiva vanobwembura mashoma okunze, nyanzvi dzinorumbidza kuchinja yose yepasi gungano. Uyewo panguva aimhanya deform muperekedzi bushings. Somugumisiro, zvinoda yokutsiva kana dzinodhura igadziridzwe humburumbira. Kana nokukurumidza uye nokukurumidza kukuru, zvingava zvakakwana kuti deform kuti pisitoni neVadzidzi vharuvhu. Vagadzirise zvinoita njere - chete kutsiva.

Ndezvipi vasingavimbiki Motors pa breakage?

Maererano nenhamba, yakakwirira tsika deformation uye kukuvadza vari DOHC michini, uyewo vezvikwata kubva Japanese vagadziri ( "Nissan", "Toyota", "Vagabond"). Kupfuura nyore uye saka yakavimbika - nayo vosmiklapannye injini ine chete camshaft (SOHC). Muri kuisa kuti "Nexia", "Lanos" uye "Lacetti".

Diesel

Chero rinotyisa nyaya kuudzwa chero eight- uye shestnadtsatiklapannye peturu michini, kupfuura migumisiro achine Diesel dzakabatana. Nekuti zvakawanda kuoma kugadzira mavharuvhu ari TDC vari asiri kufamba. Naizvozvo, kana nguva bhandi akaputsa ari Diesel muinjini, pachava deformation vanoverengeka nodes. It camshafts inobereka tsvimbo (sezviri kuratidzwa pamusoro) uye Pushers. Uyewo pasi humburumbira nechigumbuso kutsiviwa.

zvikonzero

Kune zvinhu zvakawanda, nekuti icho breakage kunoitika:

• Contact aine rabha unhani mafuta uye tsvina. Kuti zvisaitika, kuti raiva pedyo nebundu nokungwarira akavhara purasitiki kwedzimba, riri kumativi ose akakiya. Kana breakage kana yokutsiva chinhu kazhinji deform kuti casing nokuda izvo dzimwe zvinhu kuwana zvakare pamusoro pechiso mashandiro.
• Normal kusakara chaikosha kana hunoshamisa.
• Wedge mvura pombi, kana zvakafanana "pombi". It hunonyatsobatana iyi mashandiro basa.
• Wedge tensioning chinotenderera, camshaft kana crankshaft. kukuvara chikonzero kune vapedzisira maviri zvakaoma chaizvo, iyo isina pamusoro pombi kana chinotenderera.

chitsividzo

Kana chakabvamburanyiwa nguva bhandi (kana imwe motokari Vaz nayo - hazvina basa), danho rokutanga - kuisa chinhu chitsva. Shared nokuda kwezvikonzero zviviri, achitaura nezvokuparadzwa yokutsiva:

• Natural yabvaruka. Manufacturers vanokurudzira kutsiva chinhu kuita kanenge kamwe muna 80 zviuru makiromita. Zvisinei, pane zviitiko apo bhandi "akachengeta" nokuti 150-200 zviuru pasina deformation uye miridzo. Asi izvi hazvirevi kuti unogona kutakura wokutsiva ane isingazivikanwi nguva. It hwakazara rinodhura igadziridzwe.
• Zvokuimba kukuvara. bhandi mamiriro anogona zvakakuvadza somugumisiro zvikanganiso zvakakura munguva installation. musiyano ichi chinoratidza, kushomeka kana kunyanya tensioning maatomu akafanana. Uyewo vaibvisa ngaasungirire (kazhinji kungoita dzibhururuke) pamwe yezviri vatasvi "kudimbura", icho pamwe kamwe braking. Kana muchina "prochipovana" zvaizopedza cutoff, zvingangoita wakaputsika bhandi. Saka regai dzinowanzoba motokari pasi zvikuru mutoro ezvinhu.

In kuramba oparesheni zvakakosha kuteerera ukuru makakatanwa maatomu akafanana, uye sungisa kana zvakakodzera. Kuvapo zvakasiyana utachiona uye makatsemuka ayo pamusoro nezvisingabvumwi. Zviya, nedotyanuty bhandi anogona igobhururuka munembo. Panyaya iyi, mhanya pakati pfungwa pamusoro camshaft sprocket uye pokugara achava zvinopfuura chimwe sendimita.

dziviriro

To pakarepo yakabvaruka bhandi nguva (8 mavharuvhu), unofanira kutevera zvayo STRUCTURAL ezvinhu uye kuteerera injini. Kana muine mubvunzo, kuteerera gasi kugovera mashandiro. Yeuka kuti kutsiva bhandi zviri nyore zvikuru uye isingadhuri pane rokugadzirisa injini. Kana anoita maitiro squeaks kana sags kana injini washandukurwa kure, ichi ndicho chiratidzo chokutanga kuti inotaura yokutsiva kwayo. Vamwe vatyairi vanodavira kuti "inopiswa." Idzi inhema - bhandi vanofanira kushanda zvakanaka chete masekonzi yokutanga injini wokutanga. Haufaniri kurudzosa - netambo anokwanisa ruoko, saka achirasikirwa simba. Nokuda kwaizvozvi, bhandi musisiri kana ruchitedzemuka pamwe zvisiri. Kana kakawanda anoputsa, Ungangove iwe ndakagadza ari chakaremara chikamu. Kuti pakanga pasina wedges miseve uye pombi, regai overheat injini uye musaedza kurishandisa mune zvakaoma mutambo muoti.

Mari basa

Kana chakabvamburanyiwa nguva bhandi (kusanganisira 2112) pasina vaikunga mavharuvhu, mutengo yokutsiva richava pamusoro 500 rubles. Asi pasi vamwe unyanzvi unogona kuzviita nemaoko enyu. Nokudaro, bhajeti Kuparara haasi kupfuura chiuru rubles. Zvisinei, izvozvo inokurudzirwa kuongorora mamiriro ezvinhu impeller pombi uye tensioner chisimudziso - vanofanira tenderera zvakanaka, pasina ruzha, uye kutamba. Kana paiva achikanganisa uye zvinoda vharafu yokutsiva uye yokugadzirisa humburumbira chinogumbura, mutengo mabasa anogona kusvika 40-50 zviuru rubles. Kana zviri achembera wokumwe motokari, nyore akamisa chibvumirano pamwe disassembly of injini - mune zvimwe zviitiko zviri zvechokwadi isingadhuri kugadzirisa tsaru. Eya, kudzivisa mamiriro ezvinhu aya, tevedzera tatamuka maatomu akafanana uye ayo STRUCTURAL ezvinhu, uye Chikurukuru - vanochengeta yokutsiva zvikamu zviri 60-80 zviuru makiromita. Kunyange kana pashure iyoyo bhandi haisi ngozi (pasina deformations uye extraneous ruzha), hakuzovi okushamisira kutamba nayo yakachengeteka, kuisa chinhu chitsva panzvimbo yake.

Saka isu afunga zvokuita kana nguva bhandi akaputsa.
